are you sure you want to post this in this sub forum?
you might get more responses in the problems sub forum
that being said, it looks like a deficiency of some sort... mag maybe? I'm sure more will chime in

You may have spider mites. Look at the undersides and see if there is webbing and tiny black spots moving around. If it mites, it's best to get rid of them now. Those critters are the devil lol

spider mites, or something was sprayed on them. Look under the leaf, they can be seen moving. Is there any webs around the base or on leafs?

It's thrips, here's a pic..

Hi thanks to all replies ,I see no bugs, mites,webs, just specs that won't come off by rubbing. It was same plant that had seedling case stuck to it but was eventually removed without harm I think.
When I transplanted it, soil became loose and fell on underside of leaves which i just left and placed in new pot .
